High Light Transmission Polaroid Sunglasses

Does anyone know of a source for yellow Polaroid sunglasses of a fit over type  that have high light transmission ?

Both Fitover and Cocoon make yellow tinted Polaroid sunglasses; however, their light transmission is still approximately between 10 and 20%.  This is not enough different in light transmission from the amber and grey lens especially when one is fishing early or late in the day or on a markedly cloudy day.

A decade ago an optometrist made a pair of prescription Polaroid sunglass in yellow that had a light transmission of around 50%.  Unfortunately I can find no one that can do this now. Perhaps some are available via the internet , however because of my prescription it would be difficult to do an internet order.

It would seem that individuals that fish for species where it is important to identify structure would have a need for a sunglass with a high light transmission.  

I mentioned fit over type in the first paragraph because perhaps there is a sunglass out there that would not be the type like Fitover or Cocoon brand that would still fit over a very small pair of prescription glasses.

Thanks.
